28. Whenever this divine love penetrates man's hearts and shapes and guides them, they can make their own the words of Paul: "Nothing is beyond my powers, thanks to the strength God gives me;"²⁹ so that nothing can resist or frustrate their efforts - this the history of the Church teaches us. What took place in apostolic times is then wondrously repeated: "the utterance fills every land, the message reaches the ends of the world."³⁰ In them the gospel of Jesus Christ has new sowers, men quickened by divine grace whom nothing can hold back, unless it be their chains, as is sadly evident in our times; only death can shackle them; and death, when made illustrious by the martyr's palm, always stirs up new multitudes, brings forth new followers of the Divine Redeemer, just as happened in Boniface's time.
